\( 81 + 1 = 82 \)
Answer: 82
---
Part B: Write the number that is one less than the given number.
We need to subtract 1 from each given number.
1.
72:
\( 72 - 1 = 71 \)
Answer: 71
2.
63:
\( 63 - 1 = 62 \)
Answer: 62
3.

5.
59:
\( 59 - 1 = 58 \)
Answer: 58
6.
4:
\( 4 - 1 = 3 \)
Answer: 3
---
Part C: Write the number that is one less and one more than each given number on the railroad cars.
For each number, we need to find both the number that is one less and the number that is one more.
1.
Number on the car: 61
- One less: \( 61 - 1 = 60 \)
- One more: \( 61 + 1 = 62 \)
Answers: 60, 62
2.
Number on the car: 33
- One less: \( 33 - 1 = 32 \)
- One more: \( 33 + 1 = 34 \)
Answers: 32, 34
3.
Number on the car: 5
- One less: \( 5 - 1 = 4 \)
- One more: \( 5 + 1 = 6 \)
Answers: 4, 6
4.
Number on the car: 88
- One less: \( 88 - 1 = 87 \)
- One more: \( 88 + 1 = 89 \)
Answers: 87, 89
